Completely hides an element visually and positionally in the DOM while still allowing it to be accessible.
Provides an alternative to display: none (not readable by screen readers) and visibility: hidden (takes up physical space in the DOM).

  • Remove all borders.
  • Use clip to indicate that no part of the element should be shown.
  • Make the height and width of the element 1px.
  • Negate the elements height and width using margin: -1px.
  • Hide the element’s overflow.
  • Remove all padding.
  • Position the element absolutely so that it does not take up space in the DOM.
